A dramatic rise in carbon dioxide 250 million years ago may have caused global temperatures to soar and result in Earth's greatest mass extinction, according to a study published in the September issue of Geology. Global warming, which may have produced temperatures 10 to 30 degrees Celsius higher than today, would have had a significant impact both on oceans, where about 95% of lifeforms became extinct, and on land, where almost 75% of species died out.

Late last month an atmospheric scientist at Massachusetts Institute of Technology published a study in Nature that found that hurricanes have grown significantly more powerful and destructive over the past three decades. Kerry Emanuel, the author of the study, warns that since hurricanes depend on warm water to form and build, global climate change might increase the effect of hurricanes still further in coming years.

Experts say that Hurricane Katrina could produce an environmental disaster in New Orleans. Ivor van Heerden, director of the Louisiana State University Public Health Research Center in Baton Rouge, went so far as to warn "We need to recognize we may be about to experience our equivalent of the Asian tsunami, in terms of the damage and the numbers of people that can be killed."

Madagascar has been called the great red island and from space, astronauts have remarked the island looks like it is bleeding to death. Soil conditions and poorly vegetated hillsides mean Madagascar loses more topsoil per hectare than any country in the world. Being one of the poorest nations on Earth, the people of Madagascar can ill afford this loss. In 2004 I set off to see one of the rivers that is carrying away the island's soils; the Manambolo of Western Madagascar

Yesterday Brazil announced that 3,515 square miles (9,103 square kilometers) of Amazon rainforest were destroyed between August 2004 and July 2005, a marked decline from the 7,229 sq. mi. (18,723 sq. km.) in the same period a year earlier. While the government has tried to take credit for the drop, analysts say the slowing is more likely the result of lower commodity prices, giving farmers less incentive to clear forest land.

Between the 1967 and the 1990s, the Oriente rainforest of Ecuador suffered serious degradation and deforestation from Texaco's oil extraction and production activities. Today Texaco, now owned by Chevron, is facing a multi-billion dollar liability in a case stemming from its role in the environmental damage. Amazon Watch, an environmental group that has been tracking the case, says trial isn't going so well for the oil firm.

A group of scientists from Feati University in the Philippines recently devised a biological fuel cell that uses the enzyme Nicotinamide Adenine Dinucleotide (NAD) to directly convert biochemical energy into electricity. Their research raises the possibility that household pests like mosquitoes, rats, cockroaches and flies could be used as biofuel sources.

A proposal to create a refuge for African wildlife in North America has come under harsh criticism from African conservationists according to a report from Sapa-AFP.

A new report suggests that the Arctic ocean could have ice-free summers by 2100 as a result of global warming. melting is accelerating, and a team of researchers were unable to identify any natural processes that might slow the de-icing of the Arctic.

The New York Times reports that nine northeastern U.S. states are working on a plan to cap and then reduce the level of greenhouse gas emissions from power plants, the first U.S. deal of its kind and one which would see the region breaking with the Bush administration which refused to sign the Kyoto Protocol. The move raises interesting legal issues and comes as California, Washington and Oregon are considering a similar pact.

Dubai, a city-state in the United Arab Emirates, has lately embarked on an ambitious plan to boost its international standing by building a number of artificial islands. These islands, which will house luxury residences, villas, and hotels, are a growing concern for environmentalists due to their impact on the local marine ecology. Dubai should be concerned as well for the long-term viability of the plan -- rising sea levels from global climate change could spell trouble for its audacious and ostentatious investments. As Earth Island Journal puts it, "How ironic that the very people who drive rising sea levels through their businesses, which emit much of the world's greenhouse gases, will undoubtedly be some of the first to experience the devastating effects of climate change." At least Dubai will soon have the world's tallest building for its residents to escape the potential swamping.

This week policy makers, industry leaders, and development experts are meeting in Abuja, Nigeria to discuss the future of African fisheries and aquaculture. The fisheries sector, consisting of both inland (freshwater) and marine fisheries, is a vital source of food and income to millions of Africans. Fish production, processing and trade provides employment for more than 10 million, while fish exports from Africa are worth US$ 2.7 billion annually. The following is a description of the summit from Fish for All, an initiative seeking to shape public policy on issues from issues as fish and development, fish and nutrition, health, livelihood, environment, gender, water, river basins and coasts, trade and economic growth.

At the upcoming 8th World Wilderness Congress in Anchorage, Alaska, Dr. Michael Fay, a world-renowned conservationist and explorer famous for his 15-month, 2,000 mile walk through Central Africa's forests, will offer the first report on his "MegaFlyover," the yearlong survey took him through close to 50 countries and covered 100,000 miles (160,000 kilometers). Over the course of his journey in a 1960's-era Cessna, Dr. Fay snapped digital photos every 20 seconds and landed in places rarely seen by humans. His survey will help set conservation priorities for the African continent.

Two hippo stories have been in the news lately. In the first, a baby hippopotamus that survived the tsunami waves on the Kenyan coast has formed a strong bond with a giant male century-old tortoise, in an animal facility in the port city of Mombassa, Kenya. In the second, an article by Mark Grossi in The Fresno Bee, hippo sweat could soon be used to prevent sunburn and protect skin from mosquito bites. Professor Christopher Viney at the University of California at Merced is working on deciphering the molecular structure of skin secretions from the hippopotamus. The research could eventually result in the creation of skin-care products based on compounds produced by the African animal.

A recent study by the Wildlife Conservation Society (WCS), the American Museum of Natural History (AMNH), and New York University, found that a single humpback whale migrated between the Atlantic and Indian oceans, the first documentation that whales move between ocean basins. It is believed that humpback whales make annual migrations of up to 25,000 km (16,000 miles).

Currently there are three "competitive" maps of the world's biodiversity hotspots based on different criteria: (1) areas rich in species diversity in general; (2) threatened species specifically; and (3) endemic species, which have a limited habitat. A new study found that these three maps share only 2.5% of their total area, thus adding confusion to what hotspots should be priorities for conservation efforts. The overlap all occurs in the Andean region of South America, implying that this area is the world's biodiversity champion.

A study in Ukraine found that Chernobyl's ecosystems seem to be recovering just 19 years after the region was badly contaminated with radiation from a nuclear meltdown. Researchers, who presented the finding at this week's Ecological Society of America meeting in Montreal, say that biodiversity is actually higher than before the disaster.

An article in New Scientist says the world's largest frozen peat bog is melting. A million square kilometers of bog across the western Siberia is turning into a mass of shallow lakes and potentially releasing massive amounts of methane, a potent greenhouse gas, into the atmosphere.

A related article from Reuters finds anecdotal evidence of animals behaving strangely and appearing in unusual areas possibly due to global climate change.

Machete-wielding poachers killed some 80 protected Olive Ridley sea turtles on Escobilla beach in Oaxaca, Mexico last weekend. The poachers were believed to be after turtle eggs, thought to be an aphrodisiac among locals. The discovery of the massacre was announced by Profepa, the government's environmental protection agency

Scientists at the Weizmann Institute of Science in Israel think they may have developed a green process for converting solar energy into hydrogen. Currently, most hydrogen is produced by processes that require the combustion of fossil fuels which produce polluting greenhouse gases.

Mark Hertsgaard argues in a San Francisco Chronicle editorial [external link] that nuclear energy isn't a viable option in the fight against global climate change and environmentalists should abandon it as a potential replacement for fossil fuel-based technologies. Citing a study by the Rocky Mountain Institute, Hertsgaard writes that "nuclear power is seven times less cost-effective at displacing carbon than the cheapest, fastest alternative -- energy efficiency." He uses the example of a $2 billion nuclear power plant. "If that $2 billion were instead spent to insulate drafty buildings, purchase hybrid cars or install super-efficient lightbulbs and clothes dryers, it would make unnecessary seven times more carbon consumption than the nuclear power plant would," writes Hertsgaard. "In short, energy efficiency offers a much bigger bang for the buck. In a world of limited capital, investing in nuclear power would divert money away from better responses to global warming, thus slowing the world's withdrawal from carbon fuels at a time when speed is essential."

Today when Brazil is mentioned in the same sentence with "agriculture," people often first envision the Amazon rainforest giving way to soybean plantations and cattle farms. While the Amazon is being converted for such purposes, the cerrado, a vast area of savanna-like grasslands covering more than 20% of the country's surface area, is increasingly under threat as farmers from the United States and Europe are setting their sights on the biome's sizable agricultural potential.
